Description

Technical Field

[0001] The utility model relates to the technical field of visual detection, in particular to a defect detection machine for chemical fiber industrial yarn rolled products. Background Art

[0002] When chemical fiber factories produce silk, they process the silk into silk cakes of different specifications. After winding, chemical fiber silk will have defects such as hairy silk, hairy silk balls, looped silk, snagged silk, and oil stains. The above defects are often concentrated on the top surface of the chemical fiber silk cake. Therefore, in order to ensure product quality, the appearance quality of the chemical fiber silk cake needs to be tested after production.

[0003] Patent document "202211569251.2" discloses a yarn cake appearance inspection device and a control method thereof, wherein chemical fiber yarn cakes are placed on a yarn cake tray, and the yarn cake trays are arranged at equal intervals on a conveyor belt, and the yarn cake trays move with the movement of the conveyor belt; the method adopted in this patent document is to move the chemical fiber yarn cakes to the yarn cake tray one by one, and transport them through the conveyor belt for inspection, but since the chemical fiber yarn cakes themselves have a large weight, if they are transported and inspected by manual transportation, their efficiency is often very low, and damage to the product is inevitable during the transportation process. Generally, manufacturers will hang the chemical fiber yarn cakes on a yarn cart after production. Therefore, compared with the inspection method of transporting the chemical fiber yarn cakes one by one to the yarn cake tray, it is particularly important to design and develop an appearance defect detection device for the chemical fiber yarn cakes on the yarn cart. The operator only needs to push the yarn cart to the position to be inspected to complete the defect detection. Utility Model Content

[0049] See also Figure 3 As shown, as a preferred solution, the guiding mechanism further includes a blocking member 502, which is detachably fixed between the two guide plates 501. The setting of the blocking member 502 mainly plays a blocking role, which can prevent the wire car 200 from excessive displacement, that is, it can make the wire car 200 reach the correct position and wait for subsequent detection; as a further preferred solution, the blocking member 502 is a plate-like structure, and the blocking member 502 is arranged at one end of the guiding mechanism, that is, one end of the two guide plates 501.

[0050] See also Figure 4As shown, the defect detection mechanism 400 includes: a fixed plate 401, connected to the lifting Z-axis module 304; a detection plate 402, which is inclined with the fixed plate 401, and the detection plate 402 and the fixed plate 401 are connected via a connecting frame 403; a first defect detection station 404, which is arranged on one side of the surface of the detection plate 402; a second defect detection station 405, which is arranged on the other side of the surface of the detection plate 402; in the above technical solution, when the chemical fiber yarn cake 201 is hung on the silk car 200, in order to prevent the chemical fiber yarn cake 201 from falling during the movement, the chemical fiber yarn cake 201 is inclined on the silk car 200, and in order to perform appearance defect detection on the chemical fiber yarn cake 201 located on the silk car 200, the detection plate 402 It is also arranged at an inclination, that is, the detection plate 402 is arranged parallel to the top surface of the chemical fiber yarn cake 201, and the fixed plate 401 is connected to the lifting Z-axis module 304, that is, the fixed plate 401 is connected to the sliding lifting plate of the lifting Z-axis module 304; the detection plate 402 and the fixed plate 401 are connected by a connecting frame 403, and the connecting frame 403 can also play a role in angle adjustment, that is, when the inclination angle of the detection plate 402 deviates, the angle of the detection plate 402 can be adjusted by adjusting the connecting frame 403; the first defect detection station 404 is used to detect the hair, capillary balls and looped wires appearing on the top surface of the chemical fiber yarn cake 201; the second defect detection station 405 is used to detect the stray wire and oily dirt appearing on the top surface of the chemical fiber yarn cake 201.

[0051] See also Figure 4 As shown, a positioning camera 406 is fixed at the top of the middle part of the detection plate 402, and the positioning camera 406 is used for visual positioning of the defect detection mechanism 400; in the above technical solution, since the chemical fiber yarn cake 201 enters the detection space 101 through the yarn cart 200, even if a guiding mechanism is provided and a blocking member 502 is provided in the guiding mechanism, it is impossible to ensure that the yarn cart 200 can reach the correct detection position. Therefore, the existence of the positioning camera 406 can take a picture of the first chemical fiber yarn cake 201 initially located at the top, so as to feed back the information to the control system, and the position of the chemical fiber yarn cake 201 is calculated by the control system. The position information is fed back to the defect detection mechanism 400, so that the defect detection mechanism 400 is controlled by the moving mechanism to perform visual defect detection on the chemical fiber silk cake 201. It is worth noting that in most cases, visual positioning only needs to collect the position data of the first chemical fiber silk cake 201 located at the top, and the remaining chemical fiber silk cakes 201 do not need to be visually positioned. However, if the position of the chemical fiber silk cake 201 is always changing, the positioning camera 406 can also perform visual positioning for each chemical fiber silk cake 201. The positioning camera 406 is a prior art, and technical personnel in this field can select it according to actual needs.

[0052] See also Figure 4As shown in the figure, the first defect detection station 404 includes: a first fixed seat 4041, fixed to the front end of the detection plate 402; a transmission pipe 4042, which passes through the first fixed seat 4041 from the rear end of the detection plate 402 and extends to the front side of the first fixed seat 4041. A first driven wheel is fixed to the outside of the rear end of the transmission pipe 4042; a first driving motor 4043, fixed to the rear end of the detection plate 402. A first driving wheel is fixed to the output shaft end of the first driving motor 4043. The first driving wheel is connected to the first driven wheel by a first belt; a detection bracket 4044, sleeved on the outside of the transmission pipe 4042. Two first detection cameras 4045 are symmetrically fixed on both sides of one end of the detection bracket 4044. A light source 4046 is fixed to the other end of the detection bracket 4044; in the above technical solution, the light source 4046 is a planar light source. A first through hole is provided at one end of the detection plate 402. A first bearing is arranged in the first through hole. A second bearing is also arranged inside the first fixed seat 4041. The transmission pipe 4042 passes through the first bearing, the second bearing and the first fixed seat 4041 in sequence and extends to the outside of the fixed seat 4041. Thus, when the first driving motor 4043 drives the first driven wheel to control the transmission pipe 4042 to rotate, the first fixed seat 4041 does not rotate; the detection bracket 4044 is of a "C" - shaped structure. The detection bracket 4044 is sleeved on the outside of the transmission pipe 4042. The detection bracket 4044 is located outside the first fixed seat 4041. Therefore, the detection bracket 4044 can rotate with the rotation of the transmission pipe 4042, that is, the first driving motor 4043 can control the detection bracket 4044 to rotate. The first detection cameras 4045 and the light source 4046 are located at opposite ends. When detecting the chemical fiber cake 201, the light source 4046 provides light for the first detection cameras 4045, and the first detection cameras 4045 take pictures of the top surface of the chemical fiber cake 201, and then feedback the photo information to the control system. The control system judges whether there are defects such as hair filaments, hair filament clusters and loop filaments on the top surface of the chemical fiber cake 201 according to the preset information, and feeds back the information of whether there are defects through the display screen;It is worth noting that the top surface of the chemical fiber cake 201 is in a vertically inclined state when it is suspended, and when the detection camera 4045 is in the initial detection position, the detection camera 4045 is arranged downward. In addition, the purpose of setting two detection cameras 4045 is that since the middle part of the chemical fiber cake 201 has a bobbin, the two detection cameras 4045 are located on both sides above the bobbin to take pictures of the top surface of the chemical fiber cake 201, so as to facilitate more comprehensive visual collection of the top surface of the chemical fiber cake 201. Moreover, the driving motor 4043 can control the detection camera 4045 and the light source 4046 to rotate, that is, all-round visual capture and photography can be achieved. Under normal circumstances, the driving motor 4043 will control the detection camera 4045 to stop after rotating a certain angle, and then control it to rotate after the photography is completed. The detection camera 4045 is a prior art, and those skilled in the art can select it according to actual needs; in addition, the first bearing can be a ball bearing. ;

[0053] See also Figure 4As shown, the first defect detection station 404 further includes: a telescopic shaft 4047, which is inserted through the transmission tube 4042 from the rear end of the transmission tube 4042 and extends to the front side of the transmission tube 4042; a pneumatic clamp 4048, which is fixed to the front end of the telescopic shaft 4047; a servo driving mechanism 4049, which is fixed to the rear end of the detection plate 402, the telescopic shaft 4047 is connected to the servo driving mechanism 4049, and the servo driving mechanism 4049 is used to control the telescopic shaft 4047 to move forward and backward; The telescopic shaft 4047 passes through the transmission tube 4042. Therefore, the axial movement of the telescopic shaft 4047 will not affect the transmission tube 4042. At the same time, the circumferential movement of the transmission tube 4042 will not affect the telescopic shaft 4047. The front end of the telescopic shaft 4047 is fixed with a pneumatic clamp 4048. Due to the presence of the positioning camera, the positioning camera has collected the position of the chemical fiber cake 201. The moving mechanism will drive the defect detection mechanism 400 to move to the correct position, and then the servo will be driven. The mechanism 4049 works, and the pneumatic clamping claw 4048 is pushed into the bobbin of the chemical fiber cake 201 through the telescopic shaft 4047, and is stretched to grab the chemical fiber cake 201, and then the telescopic shaft 4047 is controlled to retract by the servo driving mechanism 4049, so that the chemical fiber cake 201 is located at the correct detection position, and then the chemical fiber cake 201 remains stationary, and the detection camera 4045 and the light source 4046 are driven by the driving motor 4043 to collect images of the chemical fiber cake 201. After the collection is completed, Push the chemical fiber cake 201 to its original position; preferably, in order to reduce the impact between the telescopic shaft 4047 and the transmission tube 4042, lubricating oil can be added to the transmission tube 4042, or a bearing can be arranged in the transmission tube 4042; in addition, the servo driving mechanism 4049 is a single-axis slide, an L-shaped fixed seat is fixed at the sliding end of the single-axis slide, and then the telescopic shaft 4047 is connected to the fixed seat, so that the servo driving mechanism 4049 can control the telescopic shaft 4047 to perform axial movement.

[0054] See also Figure 4As shown in the figure, the second defect detection station 405 includes: a second fixed seat 4051 fixed to the front end of the detection board 402; a rotating shaft 4052 passing through the second fixed seat 4051 from the rear end of the detection board 402 and extending to the front side of the second fixed seat 4051, with a second driven wheel fixed to the rear end of the rotating shaft 4052; a second driving motor 4053 fixed to the rear end of the detection board 402, with a second driving wheel fixed to the output shaft end of the second driving motor 4053, and the second driving wheel and the second driven wheel are connected by a second belt; a detection seat 4054 connected to the front end of the rotating shaft 4052; a second detection camera 4055 fixed to one side of the front end of the detection seat 4054; a 3D detection camera 4066 fixed to the other side of the front end of the detection seat 4054. In the above technical solution, a second through hole is provided at the other end of the detection board 402, a third bearing is arranged in the second through hole, a fourth bearing is further arranged inside the second fixed seat 4051, the transmission shaft 4052 passes through the third bearing, the fourth bearing and the second fixed seat 4051 in sequence and extends to the outside of the second fixed seat 4051, and the second driving motor 4053 controls the rotation of the transmission shaft 4052 by controlling the second driving wheel and the second driven wheel. Since the detection seat 4054 is connected to the transmission shaft 4052, the second driving motor 4053 can control the rotation of the detection seat 4054. The detection seat 4054 is of a "C" - shaped structure, and the second detection camera 4055 and the 3D detection camera are located on both sides of the detection seat 4054. It should be noted that a light source is further arranged outside the second detection camera 4055. The light source is a planar light source, and a through hole for the lens of the second detection camera 4055 to extend out is provided in the middle part of the light source. Both the second detection camera 4055 and the 3D detection camera are prior arts, and those skilled in the art can select according to actual needs. The second detection camera 4055 and the 3D detection camera 4066 are used to take pictures of the top surface of the chemical fiber cake 201, and then feedback the photo information to the control system. The control system judges whether there are defects such as oil stains, sundries and snagged filaments on the top surface of the chemical fiber cake 201 according to the preset information, and feeds back the information of whether there are defects through the display screen; the 3D detection camera performs 3D imaging, extracts the contour for calculation, and is not affected by the product or the environment.

[0055] In the above - mentioned technical solution, by setting the first defect detection station 404 and the second defect detection station 405, the defect detection of fuzz, fuzz balls, looped filaments, snagged filaments and oil stains and sundries on the top surface of the chemical fiber cake 201 can be fully realized.

[0056] The working principle of this technical solution is as follows:

[0057] First, the silk cart 200 with the chemical fiber silk cake 201 hanging thereon is manually pushed into the detection space 101, and then the moving mechanism drives the defect detection mechanism 400 to move, and the positioning camera 406 of the defect detection mechanism 400 locates the position of the chemical fiber silk cake 201, and then the moving mechanism controls the defect detection mechanism 400 to move to the preset position, and then the second defect detection station 405 works first to perform defect detection of tripped silk and oil and dirt on the first chemical fiber silk cake 201. During the working process of the second defect detection work 405, the driving motor 2 drives the detection seat to rotate, that is, it stops taking pictures after rotating a certain angle, and continues to rotate after taking pictures until the image acquisition is completed, and then the moving mechanism drives the defect detection machine 406 ... The structure 400 moves. At this time, the first defect detection station 404 performs defect detection on the first chemical fiber yarn cake 201 for hairy yarn, hairy yarn balls and looped yarn, and the second defect detection station 405 performs defect detection on the second chemical fiber yarn cake 201 for tripped yarn and oil and dirt. When the first defect detection work 404 is performing detection, the chemical fiber yarn cake 201 is firstly grabbed by the pneumatic clamp and transported to the correct detection position, and then the driving motor starts to work, driving the detection bracket to rotate, that is, it rotates a certain angle and stops to take pictures, and continues to rotate after taking pictures until the image acquisition is completed. According to this process, all the chemical fiber yarn cakes 201 on the yarn car 200 are photographed and analyzed and fed back through the control system, and the detection work is completed.
